CunningFox creates intelligent companion guides for books. Tap a highlighted name for an instant character card. Look up archaic terms, places, and concepts in a spoiler-aware encyclopedia. Review story beat summaries to remember what happened — all without spoilers.
That name looks familiar…
Anna Karenina
A man named appears in a crowded scene — but wasn’t he introduced as “Prince Stepan Arkadyevitch ” fifty pages ago? And is the same person as ? Tolstoy switches between first names, patronymics, surnames, and nicknames constantly. You flip back, lose your place, break the spell.
Moby Dick
Melville writes about the “” and the “,” assumes you know what “” means, and casually references , , and as though every reader has spent a season on a whaling ship. Beautiful prose, dense with archaic vocabulary and nautical terms no modern reader uses.
CunningFox gives you a discreet, spoiler-aware reference — encyclopedia notes for every unfamiliar term, character cards that track all the names a character goes by, and story beat summaries so you never lose the thread.
Built for the way you actually read.

Encyclopedia at your fingertips
Places, archaic terms, historical context, and nautical vocabulary — tap any highlighted term for an instant explanation grounded in Wikipedia and web sources.
Brought to life with illustrations
As you’ve seen above, every character and encyclopedia entry can be paired with beautiful AI-generated illustrations — sourced from real references — so the world of the book feels vivid and tangible.
